Expert Field Guide: Four Strike Series, Every Frame Type Covered

The most common headache on a commercial electric strike job isn't the wiring — it's showing up to find the frame won't accept the strike you spec'd. Maybe the frame wall is too thin for a flush pocket, the existing cutout is the wrong shape, or the door has a rim exit device and nobody mentioned it until you're standing there with a mortise strike in your hand. Locknetics built their electric strike lineup to handle exactly these situations, with four distinct series that cover flush-mount, no-cut retrofit, heavy-duty mortise, and rim exit device applications.

The CS Series is your bread-and-butter flush strike — it drops into a standard ANSI prep in metal or wood frames and handles cylindrical locksets and select mortise locksets. Dual voltage 12/24VDC means you wire it to whatever your panel puts out. Available in 9/16" keeper (CS450) and 3/4" keeper (CS750) configurations, with LBM (latchbolt monitor) versions that report door status back to your access control panel. At $122 for the base CS450, this is one of the most cost-effective flush strikes on the market — compare that to an HES 5000 or Folger Adam 310-4 at significantly higher price points.

The NC Series exists for one purpose: getting electronic access onto a door without touching the frame. The "No-Cut" design uses an oversized faceplate that covers the existing strike footprint completely — no routing, no Dremel work, no frame damage. This is the strike you reach for on retrofit jobs in older buildings with aluminum storefront frames or thin-gauge hollow metal where cutting a deeper pocket would compromise the frame integrity. The NC450 handles the same cylindrical locksets as the CS, and the LBM version adds latchbolt monitoring.

The MDS Series is the heavy lifter — purpose-built for mortise and cylindrical locksets where the strike needs to handle serious preload and daily abuse. Each MDS100 ships with five interchangeable faceplates (square corner, radius corner, and variations for different frame preps), so you're covered regardless of what you find when you pull the old strike plate. The fire-rated MDS100-F models carry the listings you need for fire door applications. At $372 for the base model, it's premium hardware, but it's still well under comparable HES and Von Duprin heavy-duty strikes.

The RS Series handles rim exit devices — the strikes that mount to the surface of the frame header and engage with the rim device's latch bolt. Available in two depths (3/4" for the RS210 and 1-1/4" for the RS310), with fire-rated "F" models and LBM monitoring versions across the line. The RS comes in both satin stainless (32D) and oil rubbed bronze (10B) finishes to match your exit device trim. If you're pairing electric strikes with Von Duprin, Sargent, or any rim panic hardware, the RS series is your match.

Pro-Tip: Matching the Right Faceplate Kit to the Frame

Locknetics sells faceplate kits separately for the CS and NC series, and here's where installers save themselves callbacks. The CSFP kits include both square and round corner faceplates — one kit covers both frame types. The NCFP and NCCFP kits come in two lengths: the 4-7/8" standard and the 6-7/8" extended for frames that need more coverage. And the NCWFP kits are specifically cut for wood frame applications with a wider profile (1-7/16" vs 1-1/4"). All three are available in satin stainless (32D) and oil rubbed bronze (10B). Before you order, pull the old strike plate and measure the cutout — if it's over 5 inches long, go with the NCCFP extended kit. If you're working in a wood frame, grab the NCWFP. Getting the right faceplate kit the first time means one trip to the job site, not two.

Frequently Asked Questions

What's the difference between the CS450 and CS750?

The number after "CS" refers to the keeper depth — the CS450 has a 9/16" (0.450") keeper and the CS750 has a 3/4" (0.750") keeper. The keeper depth needs to match your lockset's latch throw. Most standard cylindrical locksets use a 1/2" latch bolt, so the CS450 works fine. Mortise locksets with a longer latch bolt may need the CS750. When in doubt, measure the latch bolt projection from the face of the door.

Can the RS Series work with concealed vertical rod exit devices?

No — the RS Series is designed specifically for rim exit devices where the latch bolt exits the door at the lock rail and engages a strike on the frame face. Concealed vertical rod (CVR) devices use top and bottom latching into the frame head and threshold, so they don't use a traditional strike at all. If you need an electric release for a CVR device, you're looking at electric latch retraction built into the device itself, like the Von Duprin E996L or similar.

Are fire-rated Locknetics strikes required on every fire door?

Not necessarily. Fire-rated strikes (the MDS100-F and RS310-F models) are required when the door assembly itself carries a fire rating AND the strike is part of the latching mechanism that maintains the door's fire integrity. If the fire door uses a separate mechanical lockset for positive latching and the electric strike is only for access control convenience, some AHJs (Authorities Having Jurisdiction) may allow a non-fire-rated strike. However, the safest approach — and the one most fire marshals prefer — is to spec fire-rated hardware on any fire-rated opening. The Locknetics F-models carry the proper UL listings.

Do all Locknetics strikes work with both 12V and 24V?

Yes. Every Locknetics electric strike across the CS, NC, MDS, and RS series accepts both 12VDC and 24VDC input — no jumper changes, no rewiring, no separate SKUs. The strike auto-senses the input voltage. This is a significant advantage over some competing brands where you have to order voltage-specific models or change an internal jumper during installation.

What does "LBM" mean and do I need it?

LBM stands for Latchbolt Monitor. These models include a built-in switch that detects whether the door's latch bolt is properly seated in the strike keeper. The switch feeds a signal back to your access control panel, enabling "door forced open" and "door held open" alarms. If your building's security spec or access control design calls for door position monitoring, you need the LBM version. On government facilities, schools, and healthcare buildings, this is almost always required. For a basic office door where you just need card-in/card-out, the standard non-LBM model saves you money.
